Atomizing apparatus used for` ejecting various liquids such as paint, insecticides, etc., are already known. Except in important plants working with compressed air produced by-means of compressors or by the town supply-these plants take up very large room space and are very costly-all these atomizers are simple pumps actuated by the user, driving and discharging a sheaf of 1o atomized liquid which is notoriously inadequate in most cases for the object in view. Now the portable atomizers actually used for ejecting liquid insecticides do not allow the latter to reach the ceiling of a room when it is relativel high. On the other part, the pressure of t e atomized jet is also very low and consequently its force of penetration in the lioors for. instance is practically inexistent.

My invention relates to a portable atomizer which obviates these drawbacks. 1t is based upon the general principle described in my U. S. Patent 1,742,004, and has for its object the ejection and the atomization of various liquids `for technical, sanitary, domestic and other applications.v

My apparatus comprises substantially the utilization for the ejection and the atomization of liquids oa compressed or liquefied 3o gas bottle integral with the apparatus which is self operating owing to the application of an uncongealable pressure reducing device oi the kind described in my coending applicati'zon Serial No. 218,270, file September 8 192 The whole atomizing device of the gas bottle with its pressure reducing device and the receptacle containing the liquid to be ejected constitutes a portable apparatus very easy to handle, allowing theejection from a distance and the atomizng of all liquids for different purposes.

The apparatus allows also of ejecting from a' distance atomized jets under pressures` which may vary from the lowest to 25 kgs. per 0111.2 and more, and ot producing sheais which may reach at least, a distance of 10 meters. o

Last-ly, the apparatus according to my invention is arranged in such a manner as to allow on the one part to regulate the power by regulating the discharge pressure of the gas and on the other hand to regulate the delivery acting upon the section of assage according to the arrangement descrlbed 1n my U. S. Patent 1,714,129.

The appended drawings show a preferred embodiment of my, invention wherein when the bottleof compressed gas is open and the pressure regulated, the atomization may either be continuous or intermittent and the duration of each ejection may be controlled without again handling the bottle, by means of a detent, as with an ordinary hand compressor. This form Qty apparatus is preferably designed for atomizing paint.

Fig. 3 is a part sectional view Fig. 4e is an elevation, drawn on a smaller scale of the whole apparatus with the gas bottle and the liquid reservoir.

Fig. l1 of the appended drawing represents a portable atomizer according to my invention which comprises (a) a compressed or liquefied gas bottle 1 provided with an uncongealable pressure reducing device and` with a handle 2 according to my above men,n tioned co-pending application Serial No. 218,270 for improvements in uncongealable pressure reducing devicesl; (hl a tubular atomizer 3 connectedto the bottle by means of the coupling 4 of the liquid reservoir.

rihe tubular atomizer comprises a body 3 adjacent to the nipple e provided with a small central duct 6 on the path-of which is formed a chamber 7 having at its lower end a hollow screw plug 8. 'This tubular plug which is normally closed during the atomizing operation by means of a joint 9 allows the communication of the duct 6 with the atmosphere. rlhis joint 9 is inserted in a cup 10 carried by a detent 11 pivotally mounted at 12 in a guard 13 connected to the body 3. At its front end the duct 6 opens in another chamber 1d rovided in the front of the body- 3. The orice 'of said tube isclosed at that `point by a' valve 15 provided with a spring A 16 and with a spindle 17 which passes loosely through a plug 18 closing the chamber 14 the latter being surrounded by a threaded tube 31 in which a member 19 is fitted by-v means of a joint 20. At the back of said member a chamber 21 is provided in which the gas passing through va plug 18 concentrically to the spindle 17 may enter. An inclined duct 22 opens also in said chamber 21 and connects it with the interior of a nozzle23 rovided with an inner screwthread in which t e vliquid reservoir which may' be of the kind found on the market, the stop being taken of.

In the centre of the, nozzle 23 is placed a smaller tube 24 which screws in the member 19 and carries a tubular plunger 25. The bore of tube 24 and consequently the tube itself is connected by a conduit 26 with a longitudinal chamber 27 provided in the front part of the member 19 and in Awhich is screwed a hollow needle 28, the screwthreaded portion 281 closing the communication between the gas chamber 21 and the liquid chamber 27. In front of the member 19 is screwed a cap 29 which surrounds the needle 28 concentrically with a certain amount of play and passes through a packing 30..- The cap 29 is provided with a head 291 for its manipulation and is perforated at 31 to allow the communication of the conical seat 32 of the needle 28 with the atmosphere according to the dispositions described in my'co-pendng application, Serial No. 218,271, for improvements in adjustable atomizers.

The working of the apparatus established as shown in the drawing is as follows The operator holding the apparatus in the A hand operates the lever 2 in the desired way to cause the opening and regulates at will J the ejecting'pressure of the expanded gas according to the force of the jet coming out of the orice 31, the opening 8 being then closed by the detent 11 and the cap 29 remaining stationary in a predetermined position. When the desired pressure has been obtained the discharge may be-regulated by4 turning the cap 29 in the required direction.

It will be understood that when the detent is closed, the gas as it passes through the duct 6 forces back the valve 15 and enters the chamber 21. A portion of said gas passing through the tube 22 acts upon the surface v of the liquid contained in the reservoir 5 and causes it to rise in the tube 25, whilst the middle fillets follow their path through the bore of the needle 28`atom1zing in the space between the end of theneedle .and the outlet 31. v

.When the ejection of the liquid such as paint for example at a given point is ended, the user releases the detent which opens,

whereupon the gas'linding an issue through the tubular sto 8 escapes instantly without pushing back t e valve 1 5. When the user Vzweedse it belongs logically to the outfit of the motorist who is thus able to repair very rapidly all damages to the paint or the varnish of the body of the car.

It will of course be evident *that I do not limit myself to the particular constructions herein disclosed inasmuch as many modifications may be made therein without. departing fromthe principle of my invention.

W hat I claim'and desire to secure by Letters Patent of the United States is 1. An atomizing device comprising an atomizing nozzle, a member having a passage therethrough for conducting iiuid under pressure to the nozzle, said member having a spring-seated check valve adapted to open by the fluid pressure in the direction of the pressure flow, a vent opening to' atmosphere communicating with the atomizer in advance of said check valve, and a` manually-controlled valve for said ventopening.

2. In an atomizing device, a nozzle comprisiiig `a tubular member'having a passage therethrough for conducting fluid under pres sure to the discharge end thereof, a spring seated check valve normally closing said passage and adapted to open under the influence of pressure iluid in the direction of the pressure flow, a valve controlled vent opening to atmosphere communicating with said pas sage in advance of the check valve therein, a second passage concentric with and surrounding the rst passage, for conducting liquid to the discharge end of the member, a third passage adapted to connect said second 'passage with a supply of liquid, means orconnecting said member to a receptacle containing a supply of liquid, and a passage in said connecting means for establishing communication between the rst-named passage beyond the check valve therein and the interior of the receptacle.

In witness whereof, I have hereunto signed my name. RENE LEMOINE, NE TROUILLET.
